"Damn, the people of the Hell Demon Sect actually arranged the Water of Lethe on the outer formation prohibition, causing me a lot of losses. The devil's eyes widened, full of resentment. He withdrew the long stick, which was originally as black as ink, and it seemed a little thin, and at least half of the Yin Soul Evil Creature was lost under the impact of this wave of Lethe Water.

"Xiao Demon, that human entered the sect location of the Hell Demon Sect, and it is very likely that he will get the secret treasure inside, which is not a good thing. The three-headed yaksha said on the side, with a hint of regret and even some hatred on his face.

Originally, he could have chased Lei Yu and killed him, but he was destroyed by the demons. It's just that due to the strength of the demons, the three-headed yaksha is not easy to do, so he can only be angry secretly. To know the strength of the Demon of the Dao, it is extremely easy to kill the three-headed Yaksha.

"Indeed, these palaces may contain the secrets of the Hell Demon Sect, and that kid can't get them. It's just that now we can't get into it, we have to gather more strength. There was a hint of thought on the face of the demon demon, and he said to the three-headed yaksha: "Three-headed, you go to contact the evil ghosts and dwarfs, and I will contact the demon girl, Qingzhu and others, gather all these forces together, and gather the strength of everyone to destroy this formation prohibition." ”

"Demon Zhen, you mean to let this matter be known to a few other guys. The three-headed Yaksha asked cautiously, the look in his eyes constantly changing.

"Hmph, don't think I don't know what your idea is. You'd better put away your ghostly mind in front of me, or I wouldn't mind adding a remnant of a three-headed yaksha to my long stick. The demon glanced at the three-headed yaksha and slammed the long rod in his hand to the ground, cracking many cracks all around, spreading in all directions.

"Yes, I know. "The three-headed yaksha is one of them. The demons specialize in devouring all kinds of evil spirits and evil creatures, and the level of ferocity is incomparable in the Nether Forest. What he says is not necessarily true, but it must be followed, otherwise the consequences will be dire.

Without the slightest hesitation, the three-headed yaksha shook his bat wings, fanned a gust of wind, and headed into the distance, about to move reinforcements.

"Luckily, this barrier has kept the demons at bay. Otherwise, the consequences will be unimaginable. A cold sweat welled up in Lei Yu's heart, originally he thought that he would definitely die, but the barrier at the end of the line resisted the attack of the demon, and he undoubtedly escaped death.

"Let's take a look at what is hidden in this palace, right? I'm afraid that the Hell Demon Sect has some important things hidden in it, otherwise it would be impossible to arrange such a powerful formation to prohibit it on the periphery. Lei Yu guessed, heading towards the ruined palace.

This is a palace complex, layer upon layer, from bottom to top, one layer is more majestic than the other, but it is also more dilapidated than the other, which makes Lei Yu suspicious in his heart, and he doesn't know what is going on.

He carefully observed the palace complex, which was divided into nine floors, each connected by a spiral staircase. They seem to be separate, but there are some things connected.

"This seems to be arranged with what kind of formation, and it is a bit exquisite. Lei Yu observed for a long time, but he couldn't see what was going on. After all, he was just a fourth-order Thunder Qi cultivator, and he didn't know anything like formations, so he just made his own guess.

The first level of the palace is connected by a small path, paved with stones, and very flat. It's just that the surroundings are bleak, lifeless, and there is a very wonderful state contained in it.

Lei Yu walked along the path, surrounded by withered flowers and trees, without the slightest life. This is a dead land, Lei Yu is cautious, he doesn't know what will come out of the surrounding area.

He mobilized his own essence, and his whole body was full of righteousness, and there was a masculine aura around him, which could avoid the continuous invasion of the evil qi around him.

"The Yin Thunder Qi here is even more refined, and it is many times better than the Dao outside. If it weren't for the fact that my own essence was very strong, I am afraid that under the effect of this yin and thunder qi, I would have fainted. Lei Yu cheered up and continued to move forward, heading to the first layer of the palace.

The palace was broken, with mottled walls on all sides, and layers of fallen leaves on the ground, and the smell of decay was born, apparently many years had passed.

"The palace here is magnificent, but it is dilapidated, and I don't know what kind of thing this palace has experienced. Lei Yu sighed a little, stood in front of the palace, and did not enter it, but observed it carefully.

The palace on the first floor is made up of a huge palace surrounded by some smaller palaces, which can be considered quite spectacular. It's just that the bleak and lifeless atmosphere in the palace makes Lei Yu very uncomfortable, and he wants to get out of this palace as soon as possible.

"Could it be that these two statues are the divine residences of the Hell Demon Sect?" Lei Yu looked at the two statues standing at the door.

These two statues are more than ten zhang high, and their whole bodies are made of fine iron, one male and one female. Among them, the statue of the man was holding a long sword, his eyes were wide with anger, and there seemed to be endless anger burning in his eyes. The statue of the woman is holding a guqin, and her face is gentle, as if she is playing carefully.

Two different statues aroused Lei Yu's interest, many demon sects have their own worship mansions, devout offerings, hoping to get strength in the mansions. These two statues stood at the palace, and naturally, Lei Yu thought of the Divine Mansion.

It's just that these two statues don't have the slightest thunder fluctuation, like two mortal things. Lei Yu only looked at it for a moment, then left here and continued to walk towards the palace hall.

The main hall is very large, but also very empty, with a radius of 100 zhang, which can accommodate hundreds of people. It's just that the main hall at this time is bleak and empty, but there is an eerie and terrifying aura spreading, making Lei Yu's back feel a little cool.

"What the hell is going on?" Lei Yu muttered to himself, Shen Nian carefully observed around but found nothing.

He quickly left the main hall and walked towards the surrounding sub-palaces. These sub-palaces are only about half the size of the main palace, although they are not as majestic as the main palace, but they also have some characteristics, Lei Yu looked at these sub-palaces with interest.

"Demon Yuan Palace. "Lei Yu came to a sub-palace, called the Demon Yuan Palace. When he walked in, a scorching aura immediately poured out, rushing towards Lei Yu, making Lei Yu startled. It's just that Lei Yu, who reacted, quickly used his own qi and blood to suppress this scorching heat, and there was no discomfort.

"It seems to be a hall for refining pills, there are Dan furnaces, and there are many Dan bottles scattered among them. Lei Yu looked around, it was scattered, and there were many things scattered in this hall, which was very messy.

In the center of the main hall, a Dan furnace stands in it, simple and natural. The Dan furnace is three-legged and has many strange patterns carved on it. The underground is even connected to the earth fire, which can be used to refine pills. But at this time, the earth fire had been extinguished, and the Dan furnace was extremely cold, and it was impossible to refine the elixir.

Lei Yu picked up a pill bottle, round and smooth, it was refined from the best spirit jade, and it was used to load the pill. The value of the pill bottles themselves alone is very considerable, but at this time, these pill bottles are scattered around randomly, messy, and even some of the pill bottles have been opened, and the pills inside have been exposed, and they have lost their medicinal effect.

"It's a pity that this elixir is ineffective, otherwise, I would have made a big deal this time. Lei Yu said with some pity. He just poured out a bottle of Dan, and the pill in it had turned into powder, and the medicinal effect was no longer there, and it had become a waste pill with no use value.

He picked up the other pill bottles, wanting to gain something, but none of the pills were effective, all of them had lost their thunder power and did not have the slightest medicinal effect.

"I don't know what happened in the Dao of Lu, so that the Hell Demon Sect even ignored these pills and left here?"

The Hell Demon Sect is a first-class faction, and even the Zixiao Sect is slightly inferior. Such a powerful sect was forced to look like this, and it was completely wiped out, and the terrifying degree of this enemy made Lei Yu a little frightened when he thought about it.

Lei Yu didn't know what to say, he was just a young man who accidentally entered this palace. Soon, he put these doubts aside and went to the other vice-palaces again.

Iron Man Palace, this is the second palace that Lei Yu came to. Just hearing this name, Lei Yu didn't know what this Iron Man Hall was all about, which made him even more puzzled in his heart. It stands to reason that it is impossible for the Hell Demon Sect to arrange a useless palace, and there must be something hidden in this.

Pushing the door in, a burst of dust came to his face, making Lei Yu frown a little. The Iron Man Hall had not been cleaned for many years, and a thick layer of dust had been scattered throughout the palace, and the smell of corruption could be smelled everywhere.

Lei Yu urged his own qi and blood, forming a golden storm around him, sweeping away the dust around him, but what was presented in front of Lei Yu made him startled, it turned out to be an iron man.

"It's not really all iron men!" Lei Yu muttered to himself, walking into the palace and taking a closer look.

There are more than 100 of these iron **, scattered in the iron man hall, or standing, or sitting, with different postures, but they are all lifelike. It's just that there is no coloring, which makes Lei Yu see at a glance that these are iron men, not real lives.

"No, these iron men seem to contain strong thunder power, and there are a lot of thunder fluctuations, this is not an iron man, but a puppet. After Lei Yu observed carefully, he finally found a trace of strangeness, and there was a trace of horror on his face.

These iron men are all puppets, and all of them have very strong thunder power. If controlled, these puppets can be turned into powerful killing machines, completely painless and emotionless. In Lei Yu's mind, this Iron Man Hall seemed to be more appropriate to call it the Puppet Palace.
